When the conversation moves to the greatest heavyweight MMA fighter of all time, the name Stipe Miocic inevitably enters the picture. And that’s for a good reason. Since making his UFC debut in October 2011, the American mixed martial artist of Croatian descent has built an unparalleled track record. The former Golden Gloves boxing champion and NCAA Division I wrestler is a two-time and current UFC Heavyweight Champion with a number of records to his name: He has earned the most fight-night bonus awards in the division’s history, held the title for the longest time and defended his belt more than any other fighter before him. It’s also testament to his unwavering determination that Miocic lost the title in 2018, then trained intensely to regain the strap with a thundering TKO victory one year later. His integrity shines outside the Octagon as Stipe Miocic has been moonlighting as a firefighter-paramedic in suburban Cleveland for more than ten years. Already one of the all-time greats, his MMA journey is far from finished.
